COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 710,857, dated October 7, 1902.

Application filed August 29,1901- Serial No. 73,725. (No model.)

To (LU w/tmn it may concern:

Be it known that I, WILHELM GEIEssER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new anduseful Improvements in Cooling Apparatus, of which the following is a specification.

My invention relates to cooling apparatus, the object of the same being to provide a novel construction of device of this kind by means of which water, brine, or other liquid may be caused to traverse a circuitous passage in which it is exposed to the atmosphere, and thereby has its heat removed therefrom.

A further object of the invention is to provide a novel means of mounting and supporting the slats by which the circuitous passage is formed, which dispenses with the use of metallic nails, screws, and the like, which become rusted by the action of the liquid thereon.

Other objects of the invention will hereinafter appear, and the novel features thereof will be set forth in the claims.

In the drawings forming part of this specification, Figure 1 is a central longitudinal vertical section of my improved cooling apparatus. Fig. 2 is a transverse vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail view of one of the inter mediate posts, the slats being shown in section. Fig. 4 is a view of one of the intermediate posts with some of the slats fitted thereto. Fig. 5 is a cross-section of acorner-post. Fig. 6 is a similar view of an intermediate post. Fig. 7 is a detail perspective View showing one end of a slat.

Like reference-numerals indicate like parts in the difierent views.

In carrying out my invention I employ a hollow framework made up of the cornerposts 1, the intermediate posts 2, and the slats 3, connecting said posts. Said framework has beneath and surrounding the same a tank or receptacle 4 and may be provided, if desired, with a roof or covering 5. The roof 5 is not an essential, however, and is merely provided to protect the apparatus from the heating effects of the sun.

The slats 3 are formed upon their opposite ends with dovetail tongues 6, and the posts 1 'culate.

formed in opposite sides of "the intermediate posts 2; but in the corner posts 1 said grooves are formed on the inner sides thereof or those which lie at right'angles to each other. The grooves 7 are parallel to each other, and the grooves 8 are also parallel to each other,but the grooves 7 and 8 are set at different angles to each other, as shown. The opposite ends of each of the grooves 7'intersect the upper and lower ends of the two adjacent grooves 8, below and above the same, and the opposite ends of each ofthe grooves 8 of course intersect the upper and lower ends of the grooves 7, below-and above the same. The slats 3, whose tongued ends 6 .fit within the grooves 7 and 8, are narrower than the grooves in which they fit and the upper edge of each of said slats lies flush with the upper end of the groove in which it fits. The lower edge of each of said slats therefore terminates a short distance above the lowerend of the groove in which itfits. The lower edge of each of said slats is also located above the upper surface of the next lower slat of the series. In

this way passages 9 9 are provided between each of the slats 3 andthe next lower one through which the liquid to be cooled may pass and also through which the air may cir- A circuitous passage for the liquid is therefore provided which permits of the exposure of the liquid to the atmosphere and for the flow of the same over slats which are secured in place without the use of metallic fastening devices.

The upper groove 7* in each of the posts is parallel to the grooves 7, butis slightly nearer 11, which discharge at points above the upper end of each series of slats which make up the framework. A discharge-pipe 12 leads from the tank t to any point where it is desired to use the cooled liquid.

My device is designedparticularly for the purpose of cooling water or brine to be subsequently used in cooling beer and the like, and the operation of the same is as follows: By admitting water, brine, or other liquid through the supply-pipe 10 the same is discharged from the branch pipes 11 upon the upper of each set of slats 3. The same is then caused to drip or flow by gravity through the circuitous passage formed by said slats. It passes in a thin stream first over one of the slats 3 in one direction and thence flows through the passage 9 upon the next lower slat 3, and so on until it is finally delivered into the tank 4 at the lower end of the apparatus. In passing over the course thus traced the water or brine is spread in thin sheets and exposed to the atmosphere, a free passage for currents of air being provided between the slats of which the passage is made up. Some of the heat of the liquid is thereby removed by the direct contact of the cooler atmosphere therewith, While other portions of the same are caused to evaporate, which action serves to cool the remaining liquid. As a result when the water or other liquid under treatment reaches the tank 4 its temperature is very much reduced.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A cooling apparatus, comprising a frame made up of vertical posts, and slats connecting the same, each of said posts having diagonally-arranged grooves therein, the alternate grooves in each post being parallel to each other and the adjacent grooves being set at an angle to each other with the end of each groove intersecting the ends of the adjacent grooves, and said slats having their ends fitting respectively in said grooves,with the lower edges thereof terminating at points above the lower edges of the grooves in which they are located and above the upper surface of the next lower slats.

2. A cooling apparatus, comprising a polygonal frame made up of a series of connected vertical sides, corner-posts at the corners of said frame, side posts intermediate the ends of said sides, and slats connecting the adjacent posts along each side, each of said corner-posts having on the inner side walls thereof, and each of said side posts having upon the opposite side walls thereof, diagonally-arranged grooves, the alternate grooves in each post being parallel to each other and the adjacent grooves being set at an angle to each other with the ends of each groove intersecting the ends of the adjacent grooves, and the said slats having their ends fitting respectively in said grooves, with the lower edges thereof terminating at points above the lower edges of the grooves in which they are located and above the upper surfaces of the next lower slats.

3. A cooling apparatus, comprising a frame made up of vertical posts, and a plurality of series of slats connecting the same, a supply pipe for the liquid to be cooled, and branch pipes leading from said supply-pipe and discharging upon the upper slat of each vertical series, each of said posts having diagonally-arranged grooves therein, the alternate grooves in each post being parallel to each other and the adjacent grooves being set at an angle to each other with the end of each groove intersecting the ends of the adjacent groove, and said slats having their ends fitting respectively in said grooves, with the lower edges thereof terminating at points above the lower edges of the grooves in which they are located and above the upper edges of the next lower slats.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
